(o1.es 7 V This inventionrelates'to ventilators for buildings, and more specifically-to ventilators adapted to become part of the outside wall, and designed primarily to ventilate the air between the'ceiling and thehroof I; i I Ventilators 'inuse at the presenttime for the purpose of ventilating the dead airspace between the ceiling and a relatively horizontal roof have certain'formidable objections; snow, rain and the eleme'ntsgenerally, will enter the ventilator and while the amount of moisture that will thus enter might appe'ar to be limited, it will, nevertheless, be wholly suflicient to cause disintegration of certain parts of the interior. Among such'ventilators in use at the present time are horizontal pipes or openings, or a plurality of louvers, in both of which types of ventilators some step in the direction of preventing a portion of the rain and snow from entering iseifected, but for all practical purposes such devices as are on the market at the present time, including the two types alluded to above, large amounts of water and rain still enter and, therefore, the need of an invention which will prevent the same is highly desirable.

It is, therefore, an object of my invention to provide a ventilator adapted to form a part of a wall which will prevent any rain, sleet, snow or other elements from obtaining ingress to the interior of the building.

A further object ofmy invention is to construct a ventilator having utilities not found in any ventilators at the present time, and which will be very inexpensive and economical to manufacture.

A further object of my invention is to provide a ventilator which will not permit direct torrents of air, such as storms and tornadoes, from having direct and non-circuitous access to the interior of the building, and to perform this object without the intervention of dampers or valves, it heretofore having been common for inventions to include such a damper or valve in order to safeguard against storms and the like.

These and other objects of my invention will appear from an inspection of the drawing, in which Figure l is a cross-sectional, elevational view of my invention, showing the same forming a part of a wall;

Figure 2 is a cross-sectional, plan view taken on the lines 2-2 of Figure 1 looking in the direction of the arrows; and

Figure 3 is a perspective view of my improved ventilator.

In the several figures similar portions are designated by similar reference characters in which I is a vertical wall'above the ventilator, 2 the roof of the building,=3 the supports for the roof, 4 the dead air space betweenthe roof and ceiling, 5 the verticalwall beneath the ventilator, 6 the plaster forming the ceiling of the room, 1 the plaster laths, 8 is the top horizontal portion of my ventilator, 9 the vertical portion of the ventilator, ID a hood extending outwardly and downwardly from the top portion 9, l I is the bottom extension of II], I2 is the horizontal bottom side of the ventilator, I3 is a screen extending from the diagonal portion ID of the hood to the bottom part I2 of the ventilator, said screen being made contiguous at I4 by means of soldering and the like. I5 is the end portion of the hood, I6 is the bottom edge thereof, I! is the edge of the hood parallel with the wall of the building, I8 and I9 are the two vertical ends of the ventilator, and 29 is the open space of the ventilator formed by the ends I8 and I9, and the bottom I2 and top 8 of the ventilator.

My improved ventilator in the form of a rectangular box having a relatively long hood extending exteriorly and downwardly from one edge of said box, is set within a wall with the bricks or mortar above, below and at the sides of said ventilator. It may be constructed of any inexpensive metal and it is desirable that a plurality of ventilators be installed for each building or each area of dead air space to be ventilated. For a relatively small area two ventilators,

preferably staggered so as to get a diagonal ventilation across the dead air space, may be sufficient, although for large buildings the number of ventilators may be increased as desired. The outwardly and downwardly projecting hood member It] provides an inlet for air into the ventilator which inlet is preferably provided with a screen I3 so as to exclude dirt and other undesirable elements. For the purpose of this 'appli cation the inlet as implied in the preceding sentence is defined to be that horizontal space formed by the diagonal hood I0 and the bottom part I2 of the ventilator, and which is substantially coextensive with the screen I3 covering the same. The lower portion II of the hood l0 extends relatively far below the opening covered by the screen I3 and thus definitely and positively prevents any rain, snow or sleet from entering the inlet; lIhe hood designated by I I] and the extreme lower portion thereof by II, is provided with vertical side members I5 which prevent rain 55 or snow from entering at the inlet screen I3. The

air, therefore, entering the ventilator takes an upward course from beneath the edges l6 and I! of the hood, forcing it upward as indicated by the arrows shown in Figures 1 and 3 and enters the interior of the ventilator. The ventilator being hollow and having its entire rear side 20 exposed, serves as an unobstructed passageway of the air into the dead air space 4. With my device the dead air space between the ceiling and the roof is obviated and experience has shown that unlessthere is some ventilation for this dead air space, condensation will occur in the plaster or the ceiling of the room immediately adjacent to the dead air space and, therefore, ventilating means are quite essential. If the heretofore known means are provided for obviating the dead air space, as has heretofore been the case 'by means of ventilators which permit thee'ntra'nc'e of rain, sleet or snow, equally undesirable and disintegrating factors will result by reason of the rain andmoisture working its way through the ceiling.- 1 1 My invention is not to be understood as re-, stricted to the details set forth, since these may b modified within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as newand desire to secure by Letters Patent is: H a

1; In a ventilator system, the combination of a wall having a transverse opening, an air conduit disposed in saidopening, said air conduit comprising a tubularstructure having an open end in communication with the interior of the building, and having the opposite end substantially in alignment with the outer edge of the wall, the said last mentioned end provided with a hood extending outwardly and downwardly well below the bottom of said tubular structure, and a screen extending from the bottom of said air conduit in substantiallyhorizontal plane .to said hood whereby air is permitted to pass-through said conduit without permitting foreign matter to pass therethrough.

2. A ventilator adapted to form a part of an outside wall comprising a tubular member, one

end of said member being open and the other end provided with a downwardly and outwardly extending hood, an inlet space provided between the said hood and the bottom of said member, the said hood extending a greater distance downwardly than the width of the said inlet space.

3. A ventilator adaptedto be mounted in an opening in a wall ,for ventilating a dead air space comprising an open-ended tubular member, a hood extending outwardly and downwardly providing an air space inlet between'said hood and the bottom wall-of saidfmember, the length of said hood -from the bottom edge thereof to said inlet being greater than the width of said inlet, whereby'snow, sleet and rain are prevented from entering said inlet. 7 a 1 V JOHN KLUNDER.
